4.7 µm frame — what it decides
The UPD8828AD-A: The 4.7 µm x 4.7 µm pixel frame size places this CCD in the standard-resolution imaging class — each photosite captures a relatively large area, which improves low-light sensitivity at the cost of spatial resolution compared to smaller-pixel sensors. For a machine-vision or inspection line running at moderate magnification, the larger pixel well fills faster, so exposure times stay shorter under the same illumination — a practical advantage when the line speed is fixed.
Temperature envelope and integration
Rated for 0°C to 60°C ambient (TA), this is a commercial-grade temperature range — the sensor is suited for indoor inspection stations, lab instrumentation, or benchtop optical test equipment where the enclosure stays climate-controlled. Outside that band, dark-current noise rises and the CCD's charge-transfer efficiency degrades; a system that must operate below freezing or above 60°C needs a different sensor grade or active thermal management.
